A 4-year multidisciplinary project aimed at minimising primary-energy use in UK industry is proposed, concerned with next-generation technological solutions, identifying the challenges, and assessing the opportunities and benefits (to different stakeholders) resulting from their optimal implementation. Around 20 companies from component manufacturers to industrial end-users have expressed an interest in supporting this project. With this industrial support, the team has the necessary access and is in a prime position to deliver real impact, culminating in the practical demonstration of these solutions. The proposed project is concerned with specific advancements to two selected energy-conversion technologies with integrated energy-storage capabilities, one for each of: 1) heat-to-power with organic Rankine cycle (ORC) devices; and 2) heat-to-cooling with absorption refrigeration (AR) devices. These technological solutions are capable of recovering and utilising thermal energy from a diverse range of sources in industrial applications. The heat input can come from highly efficient distributed combined heat & power (CHP) units, conventional or renewable sources (solar, geothermal, biomass/gas), or be wasted from industrial processes. With regards to the latter, at least 17% of all UK industrial energy-use is estimated as being wasted as heat, of which only 17% is considered economically recoverable with currently available technology. The successful implementation of these technologies would increase the potential for waste-heat utilisation by a factor of 3.5, from 17% with current technologies to close to 60%. The in-built, by design, capacity for low-cost thermal storage acts to buffer energy or temperature fluctuations inherent to most real heat sources, allowing smaller conversion devices (for the same average input) and more efficient operation of those devices closer to their design points for longer periods. This will greatly improve the economic proposition of implementing these conversion solutions by simultaneously reducing capital and maintenance costs, and improving performance. The technologies of interest are promising but are not economically viable currently in the vast majority of applications with >5-20 year paybacks at best. The project involves targeting and resolving pre-identified 'bottleneck' aspects of each technology that can enable step-improvements in maximising performance per unit capital cost. The goal is to enable the widespread uptake of these technologies and their optimal integration with existing energy systems and energy-efficiency strategies, leading to drastic increases performance while lowering costs, thus reducing payback to 3-5 years. It is intended that technological step-changes will be attained by unlocking the synergistic potential of optimised, application-tailored fluids for high efficiency and power, and of innovative components including advanced heat-exchanger configurations and architectures in order to increase thermal transport while simultaneously reducing component size and cost. Important system-level components are included in the project, whose objective is to assess the impact of incorporating these systems in targeted industrial settings, examine technoeconomic feasibility, and identify opportunities relating to optimal integration, control and operation to maximise in-use performance. A dynamic, interactive whole-energy-integration design and assessment platform will be developed to accelerate the implementation of the technological advances, feeding into specific case-studies and facilitating direct recommendations to industry. Only two international research teams are capable of developing the necessary tools that combine multiscale state-of-the-art molecular thermodynamic theories for fluids, detailed energy-conversion ORC and AR models, and incorporating these into whole-energy-system optimisation platforms. This is truly a world-leading development.

Energy Storage (ES) has a key role to play as a part of whole UK and global energy systems, by providing flexibility, enhancing affordability, security and resilience against supply uncertainties, and addressing the huge challenges related to the climate change. Following UKRI investment over the last decade, the UK is in a strong position internationally in ES research and innovation. Although areas of UK expertise are world leading, there is little interaction between these areas and interplaying disciplines e.g. artificial intelligence, data and social sciences. This fragmentation limits the community's ability to deliver significant societal impact and threatens the continuity of delivering research excellence, missing opportunities as a result. Consequently, there is now an urgent need for the ES community to connect, convene and communicate more effectively. The proposed Supergen Storage Network Plus 2019 project (ES-Network+) responds to this need by bringing together 19 leading academics at different career stages across 12 UK institutions, with complementary energy storage (ES) related expertise and the necessary multidisciplinary balance to deliver the proposed programme. The aim of the ES-Network+ is to create a dynamic, forward-looking and sustainable platform, connecting and serving people from diverse backgrounds across the whole ES value chain including industry, academia and policymakers. As a focal point for the ES community, we will create, exchange and disseminate ES knowledge with our stakeholders. We will nurture early career researchers (ECR) in ES and establish ambitious, measurable goals for equality, diversity and inclusion (EDI). We will complement existing activities (e.g. Faraday Institution, UKERC, Energy Systems Catapult, CREDS, other Supergen Hubs) to serve the UK's needs, delivering impact nationally and internationally. The ES-Network+ will convene and support the ES community to deliver societal impact through technological breakthroughs, generating further value from the UKRI ES portfolio. It will be a secure and inclusive eco-system for researchers in ES & related fields to access, innovate, build and grow their UK and international networks. It is distinctive from the current Supergen Storage Hub: We have a PI with non-electrochemical background, an expanded investigator team with complementary expertise in energy network integration, mechanical and inter-seasonal thermal ES, hybrid storage with digital knowledge, cold storage, transport with ES integration, ES materials measurement & imaging and social science with policy implications. Early career researchers will hold key positions within the ES-Network+ and we will underpin all of our work with EDI values. We will develop an authoritative whitepaper for steering ES related decision-making, giving an overview of the ES community and a technical view on how ES research should be steered going forward. The team is extremely well-connected to the ES industry and the wider energy community and has secured 57 supporting organisations, including energy production, transmission, distribution & network operation, specialist aggregators of heat & power, storage technology developers and integrators; ES related manufacturers, ES related recycling; and research institutes/centres/hubs/networks/associations both nationally and internationally. The supporting organisations also bring in a significant amount of extra resources to ensure a successful delivery of the ES-Network+.
